This section covers basic electronics tutorials in various electronics domains. If you are an absolute beginner, this section is the starting point to learn the basic electronics concepts. Once you are the done with understanding the basic concepts, head towards the electronics circuits section and try your hands on few circuits.
In this Physical AI tutorial, we will train a real robotic arm using Hugging Face LeRobot and imitation learning. The project uses the Seeed Studio SO-ARM101 leader–follower robotic arm and a reComputer J4012 powered by NVIDIA Jetson Orin NX.

In this tutorial, we’re going to learn how to send data from an ESP32 to Firebase Realtime Database. We are using ESP32 Firebase Google as our cloud platform. A lot of cloud-based IoT projects on YouTube / GitHub / similar platforms using ESP32, ESP8266, UNO R4, or similar microcontrollers use Firebase as the cloud platform. And this guide covers the complete ESP32…
We're all familiar with live GPS tracking; it tells us where a vehicle or device is right now. But what if the system could do more than just show the location? That's where geofencing using IoT comes in. Imagine receiving an instant alert the moment a vehicle leaves home, reaches college, enters the office, or moves into a restricted area. Instead of…
Imagine you've just sent a parcel through a courier service. As soon as it leaves your hands, you start wondering what is happening to it. Is it being handled carefully? Has it been dropped or damaged? Is it still on the right route? Will it reach the destination safely and on time? The truth is, once we send a parcel, we have very little idea about what happens…
This DIY tutorial is all about making our home lighting smart and fun without any complicated steps. We can connect a standard 12V LED strip to a tiny wi-fi chip and build our own ESP32 WLED controller custom smart lighting system, which can be completely controlled from a smartphone or computer.
This DIY ESP32 based WLED controller…
In this tutorial, we are going to see how you can create a custom Graphical User Interface(GUI) using LVGL and our favourite Arduino IDE. You can use any kind of microcontroller for this project; the only thing you need to do is to include the right pins in the Arduino code. Here, I’m using an ESP32-C3 based smartwatch for the demonstration. This has a display, touch, controller and…
From blinking LEDs to building robots, the Arduino UNO was the development board that made electronics feel possible for students, professionals and a lot of hobby makers around the world. While keeping the familiar idea of Arduino UNO and its form factor the same, they have launched this board called the Arduino UNO Q, which is a more capable variant of the original…
Bluetooth communication is everywhere. Due to its low power consumption, we can see it in a lot of our day-to-day gadgets. Behind the scenes, it's all about signals. Let’s explore what really happens when data is transmitted or disturbed via Bluetooth. This project is based on an ESP32 and two NRF24L01 modules, and we are going to learn how we can generate a 2.4 GHz…
Voice control technology has become an important part of modern human-machine interaction. It allows users to control electronic devices and systems using simple spoken commands instead of traditional input methods such as buttons, switches, or touch screens. This type of interaction makes devices easier to use, more accessible, and more convenient in many…
We love tinkering with our LiteWing ESP32 drone, and this time we gave it a simple but exciting upgrade, a WiFi camera module! With this addition, the drone can now stream live video while flying, perfect for hobby flights, aerial experimentation, or just having fun seeing the world from above.
On the technical side, the setup…
In this project, we upgraded LiteWing, an ESP32-based development drone by adding a lightweight Bluetooth speaker system to extend its capabilities beyond flight. By adding a simple Bluetooth audio setup, the drone can now deliver real-time announcements, voice messages, or music directly from the air without requiring any additional coding. The entire system works…
Voice control has become an integral part of modern smart home automation. In this tutorial, we build a voice-controlled LED system using the ESP32-S3-BOX-3 development board, combining wake word detection, speech recognition, touch interface, and audio feedback to create an intelligent control system. The code will be based on the factory example provided by…
